| 摘 要： | 尺度效应、非一致性、随机性和结构性是渗透性参数的四大特征，通过分析比较独立离散参数法、连续相关参数法、离散相关参数法、条件模拟，认为地质统计学的理论与方法是非均质问题研究的理想工具，并提出了今后研究的趋势。

| Abstract: | The statistical approach has been applied increasingly to groundwater flowproblem in the last thirty years. This development has been motivated by the rocognitionof the fact that aquifers are heterogeneous. In the present paper, the previous research onaquifer heterogeneities is reviewed. Permeability parameters vary in an irregular manner inspace, and are regarded as stochastic function. Scale-dependence uniformity stochasticvariation and spatial correlated structure are presented. The four types of stochastic methods applied to simulate the permeability parameters are summarized. Many of stochasticmethods partially describe the characterization of aquifer heterogeneities and allow the parameters to fluctuate at the points which parameter value has actually measured. Conditional Simulation can represente the variability and fluctuation of the permeability parameter in the space by conditioning the model on measured value aquifer parameters. It is suggested that geostatistics is essential to research the aquifer heterogeneities. The areas ofinterest for future research are indicated. |
